Define "contemplate" :) Carved out time to "sit and think"? I consider this a suspect method, because undirected thinking on demand is difficult. (It might work for you. It doesn't for me) Carved out time to contemplate a specific problem? Depends on how many big problems are at the stage where that makes sense. I'd say 1-4h/week. Making random connections and sort-of daydreaming about them for 5 minutes? All day, every day. It ends up in a commonplace book. I don't currently review the book, the act of taking the note alone is valuable enough. If I notice I keep thinking about something, I transfer it into a doc and grep through that during directed sessions.
